Abstract

This study undertook to assess the effects on morbidity and mortality of earlier and more frequent dialysis in acute renal failure and the rate and extent of return of renal function after recovery. From January 1955 through June 1967, 325 patients with acute oliguric renal failure or acute exacerbations of chronic renal failure underwent dialysis. Two hundred with presumed acute renal failure (no history of parenchymal renal disease) were reviewed. Two groups were compared: those dialyzed after onset of uremia or with urea values exceeding 400 mg/100 ml and those dialyzed earlier and more frequently to prevent uremia. Return of
